ERNEST LEE, OF SPRINGFIELD, ILLINOIS.

ROAD-GRADER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed May 29. 1907- Serial No. 376337.

T 0 all whom it may concern:

Be it known that I, ERNEST LEE, a citizen of the United. States,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented a new and useful Road- Grader, of which thefollowing is a specification.

This invention has relation to road graders and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a road grader of simple anddurable construction and which is provided with a set of runners mountedupon bell crank levers and means for operating the levers whereby therunners maybe brought in contact with the ground and the grad er pro erelevated above the surface of the groun and by means of which the gradermay be readily transported from point to point without operating uponthe surface of the ground.

In the accompanying drawing :-Figure 1 is a top plan view of the grader,and Fig. 2 is an end elevation of the same, the heavy lines showing thepositions of the parts when the runners are upon the ground and thedotted lines showing their positions when the runners are elevated abovethe ground.

The grader consists of the front beam 1 and the rear beam 2 which areheld in arallel relation to each other by the cross ars 3. The loweredge of the beam 1 is provided with a forwardly extending flange 4 andthe curved plate 5 is riveted or otherwise attached to the beam 1 andbears against the edge of the flange 4. The concavity of the plate 5 isforwardly disposed. The end bars 3 are provided with bearings 6 and thebell crank levers 7 are provided with pins 8 which are journaled in thesaid bearings. The runners 9 are ivotally attached to the lower ends ofthe be 1 crank levers 7 and lie beyond the ends of the beams 1 and 2.The rod 9 is pivotally connected to the bell crank levers 7. The upperportions of the rear levers 7 are extended into the handles 10, each ofwhich is provided with a spring actuated pawl 11. A gear segment 12' ismounted upon the bar 3 adjacent the handle 10 and is adapted to beengaged by the spring pawl 11 thereof. The operators seat 13 is mountedupon the intermediate cross-bar 3 and the latform-boards 14 are locatedat each side 0 the seat 13 and are attached at their ends to the beams 1andr2.

l The lower edges of the plate 5 and the beam 2 are adapted to engagethe surface of a roadand operate upon the same for the purpose ofleveling the same. As the lower edge of the plate 5 is forwardlydisposed it has a tendency to cleave the earth while the earth engagingportion of the beam 2 is vertically disposed and scrapes the surface ofthe road. When it is desired to transport the grader from one point toanother without operating upon the surface of the road the handles 10are swung so that the bell crank levers 7 are turned and the runners 9are forced down into contact with the ground and the beams 1 and 2 andtheir attachments are elevated. The outer cross-bars 3 are provided withthe clevises 15 to which the draft animals may be attached and the saidanimals may be so directed as to draw the implement along the roadat aright angle to the same or at an acute or an obtuse angle as desired. 7

Having described my invention what I claim as new and desire to secureby Letters- Patent is i 1. In a grader, a beam having a forwardlyextending flange at its lower edge, a concaved plate attached to thebeam and bear-' ing against said flange and having its concaved sideforwardlydisposed.

2. A grader comprlsing beams, spaced bars connecting the same together,a set of levers' fulcrumed upon each bar, a runner pivotally connectingwith the levers of each set and means for swinging the levers of eachset simultaneously.

3. A grader comprising beams, spaced bars connecting the beams together,a set of levers fulcrumed upon each bar, a runner plvotally. connectingwith the levers of each set, a rod pivotally connecting with the leversof each set, one lever of each set having a handle end and means forconfining each set of levers in an adjusted position.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
